Drupal Admin Audit Trail Denial-of-Service Vulnerability

A denial-of-service vulnerability has been identified in the Drupal Admin Audit Trail module, affecting versions prior to 1.0.5. This vulnerability arises from the module's inadequate handling of large values in the User Authentication submodule, which logs user authentication events. The lack of proper limits allows for excessive resource allocation, potentially leading to performance issues.

Impact

Exploitation of this vulnerability can cause a denial-of-service condition, where the application may become unresponsive or slow due to excessive resource consumption.

Remediation

Users are advised to upgrade to Admin Audit Trail version 1.0.5.
